United States Patent 2,909,812 v SEAL FOR WINDOW HAVING AIR CONDITIONERAbe Pritzert, Philadelphia, Pa. Application September 16, 1958, SerialNo. 761,379

2 Claims. (Cl. 20-52.4)

This invention relates to an attachment for a window and moreparticularly to an attachment to seal the open space between the sashesof a double hung window when an air conditioner or some othercomparatively bulky device occupies the lower part of the Window.

An object of the invention is to provide a window attachment which iseasy to handle for both installation and removal, the attachmentconstituting an effective weather seal between the upper frame member ofthe lower sash and the glass of the upper sash of a double hung windowwhen the lower part of the window frame has an air conditioner supportedtherein.

It has become customary for windows having air conditioners, to seal theopen space between the sashes by nailing, tacking or otherwise rigidlysecuring a sealing member of one type or another between the windows. Itthen becomes impossible to clean the outer surface of the inside sashand the inner surface of the outside sash glasses to completion. Thisinvention solves the problem that is presented by the now popular windowair conditioner, enabling the windows to be more easily manipulated sothat the surfaces of the window glasses may be cleaned. This isaccomplished by an attachment that is separably connected at the upperpart of the lower sash by a unique clamp or a pair of clamps at the endsof a strip that occupies the space under discussion.

A more specific object of the invention is to facilitate window cleaningand have a very effective weather seal between window sashes of airconditioner supporting windows, by using a strip having a pad thereonwith the pad adapted to contact the glass of the outside sash and theupper frame member of the inside sash, together with very easilyoperated clamps at the ends of the strip which 2,909,812 Patented Oct.27, 1959 on, together with a window sill 18. Air conditioner 20diagrammatically represents any manufacturers make of air conditioner orother appliance which may be disposed in the window opening. The windowhas two conventional sashes 22 and 24, each provided with a window paneor glass 26 and 28 respectively.

Attachment 30 is composed of a flat strip 32, preferably of light weightmetal, for instance aluminum alloy, to gether with a flexible pad 34adhered to the lower surface of the strip 32. The pad may be made offelt, rubber or some other flexible material capable of functioning asan effective weather seal. The connection between strip 32 and pad 34may be made in a number of ways, for instance it may be cemented inplace.

The two ends of strip 32 are made in an identical manner. Each has aforwardly opening notch or recess 38 to fit around the sides of theframe 16 of the upper sash 24. An edge portion 42 of pad 34 protrudeslaterally outwardly from the edge 44 of strip 32, and the part of pad 34adjacent to notch 38 also has a notch 46 therein. The two notches, then,accept the side frame members of the upper sash 24 when the attachment30 is applied to the window.

engage the confronting sides of a conventional window frame, firmlygripping them and keeping the window in place. However, the attachmentis easily removed inasmuch as one or both of the clamps is madeadjustable between open and window frame side engaging positions.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawing forming a part hereof, whereinlike numerals refer to like parts throughout and in which:

Figure l is a front perspective view of a window having an airconditioner therein and an attachment between the sashes of the window.

Figure 2 is an enlarged sectional view taken on the line 22 of Figure 1.

Figure 3 is a sectional view taken on the line 3--3 of Figure 2.

Figure 4 is a fragmentary perspective view of one end of the attachment.

Figure 5 is a fragmentary perspective view of a modified form of theattachment.

In the accompanying drawings there is a conventional window 10 havingsides 12 and 14 of the frame 16 there- There are means for fastening theattachment 30 in place as shown in Figure 1. These means consist of twoidentical clamps 50 and 52 respectively, although it is within thepurview of the invention to use a clamp only on one end of theattachment, should this be desirable. Typical clamp 50 is made of a fiatspring 54 having two'upturned ends or parts 56 and 58. The part 58 is afinger grip, and part 56 is adapted to engage the surface of side 14 ofthe window frame in order to grip against it and hold attachment 30firmly in place. Spring 54 has a slot 60 between its ends, through whichthumb screw 62 is passed. The thumb screw is also passed through awasher 64 and engaged in a threaded opening 66 near the end of strip 32.Accordingly, spring 54 may be tightened in place by thumb screw 60 orpermitted to be adjusted in a direction parallel to the longitudinalaxis of the flat, elongate strip 32. When adjusted outwardly of strip32, it is in the window frame side gripping position. When adjustedinwardly, the attachment 30 may be easily lifted from its place on theupper member 23 of the lower sash 22.

In use, strip 32 is placed with its pad 34 flush against the uppersurface of the frame member 23. The clamps 50 and 52 are adjusted sothat they have their outer ends frictionally gripped against theconfronting surfaces of the sides 12 and 14 of the window frame. Withthe edge portion 42 of the pad gripped firmly against the glass 28 ofglazed sash 24, and the notches 46 in the pad firmly contacting thesides of the upper sash 24, an eifective weather seal is produced. Yet,the attachment 30 is very easily removed when it is desired to clean thewindows, by making looseeither clamp 50 or clamp 52 and lifting theattachment from its place on the upper part of lower sash 22.

Reference is now made to Figure 5. This embodiment of the inventiondiffers from the embodiment in Figure 1 by only one particular.Attachment 30a has pad 34a made with one or more slits 68 so that theparting strips 70 of the multi-light upper sash 24a are accepted in thepad. Any number of slits 68 may be used depending on whether the uppersash has one or more parting strips.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly, all suitable modifications and 3 equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

1. An attachment for a window having a window frame provided with asill, an upper glazed sash, a lower glazed sash in the open position toreceive an air conditioner on the sill and beneath the lower member ofthe lower sash frame, said attachment comprising a strip disposedbetween the sides of the window frame and above the upper member of thelower sash frame, means separably fastening said strip between saidwindow frame sides, said fastening means including a fiat spring at oneend of said strip, and a flexible pad attached to said strip and havinga. lower surface in contact with said lower sash upper member and havingan edge portion protruding outwardly beyond the adjacent edge of saidstrip and engaging the glass in said upper sash, and said pad havingnotches in the ends thereof to accept the side members of the frame ofthe upper sash.

2. The attachment of claim 1 wherein said pad which projects beyond oneedge of said strip has at least one slit to accept a parting strip inthe upper sash.
